Background
Most of the weight loss with the BioEnterics intragastric balloon (BIB) has occurred during the first 3–4 months. This study aimed to evaluate the effect of initial weight loss on long-term weight maintenance.
Methods
From 2008 to 2011, 50 patients who had mean body mass index (BMI) of 44.7 ± 12.4 kg/m2 underwent BIB therapy for 6 months. All patients were given a diet of 1,100 kcal/day. Weight loss parameters [absolute weight loss, BMI loss, percentage of body weight loss (BWL%), and percentage of excess BMI loss] were recorded at the baseline, 1 month, 6 months (time of BIB removal), 12 months, and 18 months from the baseline. Successful weight loss was defined as ≥10 % weight loss after 6, 12, and 18 months.
Results
Twenty-seven patients (54 %) achieved a percentage of BWL ≥ 10 at the time of removal. Eighteen (36 %) and 12 (24 %) patients were able to maintain weight loss of 10 % at 12 and 18 months. Percentage of BWL after 1 month was positively correlated with BWL% after 6, 12, and 18 months (r = 0.77, 0.65, and 0.62, p < 0.001, respectively). Twenty-four patients who lost 5 % of the BWL after 1 month of treatment succeeded in maintaining a lasting percentage of BWL ≥10 after the BIB removal: more precisely, this cutoff point was achieved in 96 % at the time of removal and in 71 %, 50 % at 12 months, and 18 months of follow-up.
Conclusions
Five percent BWL after 1 month of treatment may be a predictor for long-term weight maintenance.
